i~' • • <br />be v®ry easily intercepted by the road to the west of the site, yr snor~ <br />~pecilSaally by the borrow ditch in the road west oP th9 site. S'he <br />water could then be turne8 north along the road and enter Brackett Crn~ <br />north of the land fill site. Part of this water should be diverted <br />~, swth o! the site. This can be Bone with a ditch along the south <br />'~ boundary, capable of carrying about ~0 eta. Such a ditch would have <br />a bottom width of approximately 8 ft. and a depth o! approximately 3 <br />ft., if it is designed as a trapezoidal ditch type. This ditch should <br /> run across the SNi quarter o! Section 24 and discharge almost directly <br /> into Brackett Creek close to that point. This ditch should be seperat <br /> <br /> from the land fill operation by leaving the native soil for a distance <br />of at least to ft. north of the ditch line, Eventually the land 1111 <br />would act ae a ditch bank in itself. <br />This system of ditches would protect the land fill <br />site from water entering the area from higher ground to the southwest. <br />That rainfall rdhlch falls on the land fill area should move northerly <br />or easterly along the surface of the sloping lan8 fill cover. gear the <br />edge of the land fill area, the ditch should be constructed and main- <br />~~ „ tained, which would divert the water to a direction nearly parallel <br />with Brackett Cr®ek. The grade on this ditch should be rather shalloM.~ <br />A gradient between .5% and 1% is suggested. This will allow the <br />water to move more or lees parallel to Brackett Creek and infiltrate <br />~l the ground slowly, eo that it will not pollute the groundwater. In <br />t <br />eflect, it will be sand filtered. The surface of the Lill cover itself <br />should be diked at the end of the operation, eo that water will not <br />9 <br />
